  # S3 method for detpointprocfamily
reach(x, …)

Arguments

x

Model of class "detpointprocfamily" or "dppm".

…

Additional arguments passed to the range function of the given model.

Value

Numeric

Details

The range of interaction for a determinantal point process model may defined as the smallest number $R$ such that $g(r)=1$ for all $r\ge R$, where $g$ is the pair correlation function. For many models the range is infinite, but one may instead use a value where the pair correlation function is sufficiently close to 1. For example in the Matern model this defaults to finding $R$ such that $g(R)=0.99$.

Examples

# NOT RUN {
reach(dppMatern(lambda=100, alpha=.01, nu=1, d=2))
# }
